Activity for K & W Wedding

So our theme is romantic seaside. Our colors are Aqua and grey. I'm having such a hard time finding centerpieces that I like that won't cost me an arm and leg. We're most likely having 20 tables. Ive looked on Pinterest and the web but nothing stuck...

Looking for unconventional ways to replace the traditional wedding cake other than cupcakes. Did anyone do a dessert table? Pies? Cake pops? Pictures please!

We are thinking about doing cupcakes and a smaller cake for our wedding instead of a big cake. Has anyone ordered cupcakes from Publix and would recommend them? Thanks!
